HAMAMATSU, Shizuoka Prefecture--The N700S is to bullet trains what Superman is to superheroes--Supreme.

Well, that's the idea, as the “S” logo emblazoned in gold on the new Shinkansen derives from that unsurpassable English word.

Central Japan Railway Co. (JR Tokai) hosted a preview of the prototype featuring a boxy front at its factory located here on March 10.

The N700S series will debut on the Tokaido Shinkansen Line between Tokyo and and Shin-Osaka in fiscal 2020 after finishing trial runs.

Masayuki Ueno, 61, deputy director-general of JR Tokai's Shinkansen Operations Division, said, “The (N700S series) has been completely redesigned through renovating main facilities and equipment.

“We have produced a train that can symbolize a new era for the Tokaido Shinkansen Line.”

All seats, which will be more comfortable than before, will come with electrical outlets. The overhead rack will light up when the train arrives at stations to help passengers remember if they've forgotten any luggage.

The total weight of the drive system for a 16-car variation has been reduced by 11 tons, partly by adopting a motor 70 kilograms lighter.

The N700S series will have only two types of cars, except for the head and tail cars, thanks to streamlined underfloor equipment. By comparison, the current-generation N700A series has six types.

JR Tokai hopes the fewer number of car types will boost sales of the new Shinkansen to other railway operators, including those overseas, because it allows for more flexible variations, such as an eight-car train and a 12-car train, instead of the standard 16-car format.
